Changing the number of periods for the moving average also affects the number of periods used to calculate the standard deviation. Therefore, only small adjustments are required for the standard deviation multiplier.
An increase in the moving average period would automatically increase the number of periods used to calculate the standard deviation and would also warrant an increase in the standard deviation multiplier. Bollinger suggests increasing the standard deviation multiplier to 2.
W-Bottoms were part of Arthur Merrill's work that identified 16 patterns with a basic W shape. In particular, Bollinger looks for W-Bottoms where the second low is lower than the first but holds above the lower band. There are four steps to confirm a W-Bottom with Bollinger Bands. First, a reaction low forms.
This low is usually, but not always, below the lower band. Second, there is a bounce towards the middle band. Third, there is a new price low in the security. This low holds above the lower band. The ability to hold above the lower band on the test shows less weakness on the last decline. Fourth, the pattern is confirmed with a strong move off the second low and a resistance break.
First, the stock formed a reaction low in January black arrow and broke below the lower band. Second, there was a bounce back above the middle band. Third, the stock moved below its January low and held above the lower band. Even though the 5-Feb spike low broke the lower band, Bollinger Bands are calculated using closing prices so signals should also be based on closing prices. Fourth, the stock surged with expanding volume in late February and broke above the early February high.
M-Tops were also part of Arthur Merrill's work that identified 16 patterns with a basic M shape. According to Bollinger, tops are usually more complicated and drawn out than bottoms. Double tops, head-and-shoulders patterns, and diamonds represent evolving tops. In its most basic form, an M-Top is similar to a double top. However, the reaction highs are not always equal.
The first high can be higher or lower than the second high. Bollinger suggests looking for signs of non-confirmation when a security is making new highs. This is basically the opposite of the W-Bottom. A non-confirmation occurs with three steps. First, a security creates a reaction high above the upper band. Second, there is a pullback towards the middle band.
Third, prices move above the prior high but fail to reach the upper band. This is a warning sign. The inability of the second reaction high to reach the upper band shows waning momentum, which can foreshadow a trend reversal. Final confirmation comes with a support break or bearish indicator signal.
The stock moved above the upper band in April. There was a pullback in May and then another push above Even though the stock moved above the upper band on an intraday basis, it did not CLOSE above the upper band. The M-Top was confirmed with a support break two weeks later.
Also, notice that MACD formed a bearish divergence and moved below its signal line for confirmation. Price exceeded the upper band in early September to affirm the uptrend. After a pullback below the day SMA middle Bollinger Band , the stock moved to a higher high above Despite this new high for the move, price did not exceed the upper band.
This flashed a warning sign. The stock broke support a week later and MACD moved below its signal line. Notice that this M-top is more complex because there are lower reaction highs on either side of the peak blue arrow.
This evolving top formed a small head-and-shoulders pattern. Moves above or below the bands are not signals per se. On the face of it, a move to the upper band shows strength, while a sharp move to the lower band shows weakness.
Momentum oscillators work much the same way. Overbought is not necessarily bullish. It takes strength to reach overbought levels and overbought conditions can extend in a strong uptrend. Think about it for a moment. The upper band is 2 standard deviations above the period simple moving average.
Suddenly failing to reach the bands can signal fading momentum. It tried to pull away, but bears were always in control.
There are two types of tops that you need to know about:. This signal is usually accompanied by an RSI divergence. The screenshot below shows both scenarios. The first is the top after a divergence. You can see how the trend became weaker and then eventually failed to reach the outer Band before reversing.
I marked the second spike with an arrow which was a trend continuation signal as price failed to break higher during the downtrend. The strong spike that was followed by a fast rejection showed that bulls lacked power.
